Hi Gasbags,
With regard to E.coli contamination of AD spent supernatant, I have found that
fully bio-reacted material from plants such as the BioBowser have a zero
E.coliform plate count as per laboratory analysis.
I used the Environmental Analysis Laboratory in Lismore NSW for such tests who
have also provided total elemental analysis for the chemical content of
previous batches of AD experiments.
I have also inadvertantly exposed broken and cut skin of my hands and fingers
many times to spent materials with no infection or other adverse reaction
occuring.
I don't usually submit myself to guinea-pig experiments, but in this case I
came out clean.
I did of course, sometime after the exposure, wash my hands, well before going
home.
Peter.
